Bind multiple models to one View Controller in laravel

I am starting to give up on laravel for not being able to follow a certain pattern that I always have been taking for granted !!

let's assume I have the example from this link https://laravel.com/docs/5.4/container#introduction

public function show($id)
{
    $user = $this->users->find($id);

    return view('user.profile', ['user' => $user]);
}

This user model is bound to that controller to be shown in the view. What if I need to inject another model, let's call it plane which is independent from users model (no DB relation). So that I have both of them listed in the same view.

In Angular for instance I could create multiple components on the same page and each have their own independent controllers and models.

Simply put, One controller can send request to multiple models to update single view, So yes you can use multiple models in one controller

yes you can bind multiple models with laravel like this :

public function show(User $user, Plane $plane)
{
    return view('user.plane', compact('user', 'plane')]);
}

and as @apokryfos said your example does not have any binding in the controller,

this is an example for the corresponding route:

Route::get('/fakeRoute/{user}/{plane}', 'FakeController@show');

link example:

yourSite.com/fakeRoute/1/25

Laravel supports contextual binding.

It also has shortcuts for binding database models:

Model binding

In your RouteServiceProvider you can have:

Route::model("user", App\User::class);

Then your route declared as:

Route::get("/users/{user}","UserController@show");

And your controller:

public function show(User $user) {
   //$user->id is based on the {user} route parameter
}

Other contextual binding

Route::bind("plane", function ($id, RouteInfo $routeInfo) {
      // Get the plane object based on the given $id and optionally the extra route info parameters
     return $planeObject;
});

Your route can be declared as:

 Route::get("/planes/{plane}", function (Plane $plane) {
      //$plane will depend on passed parameter
 });

Laravel also supports normal binding:

In your AppServiceProvider you can have:

 $this->app->bind(Plane::class, function ($app) {
      //Make a plane class object
     return $planeObject;
 });

Then in your controller method (or any place where Laravel allows dependency injection to occur) you can do:

public function show(Plane $plane) {
   //Plane is the globally declared binding
}

You can also combine the two e.g:

Route::model("user", App\User::class);
$this->app->bind(Plane::class, function ($app) {
      //Make a plane class object
     return $planeObject;
 });

 Route::get("/users/{user}","UserController@show");

 public function show(User $user, Plane $plane) {
   //$user->id is based on the {user} route parameter and $plane is resolved using the service container
}
